Be it known that I, Tnonms VErTcn, a eitizenofthfeUnited States, and a.resident of Dpn ont, in the county of Ber on and State of 'New Jersey,have invente certainnew and useful Im rovernen'ts in. Shock-Absorberswich. t .e... o lei ing.is. a specificatio When driving motor vehicles orany other vehicles over a rou bread or when on an even read, the wheeofthe same strike a stone oran obstruction in the road, the shock orjarwhichis ivento. thes ring sup orted bod vof the ve jcle is veryobjections, le.

tions, These devices, however, by reason of theirelasticit and thefreedom of movement cause erecoi shock which is almost as disagreeableand objectionable asthe shocks of 26 a vehicle having no shock absorbersat all.

It is now the object of the resent invention to provide an improved srock absorber, ha ving. means for controlling the movement orvibrationsof the spring-supported body of .a. vehicle relative t6 the running gearof the same, obviating the defects hercinbeforc mentioned. Such a devicecan be carried out in various ways, according to the (1011- struction ofthe vehicle to which it is applied, 36 end the drawings forming 1, artof the present application, s ow a few preferred forms of the invention.

The device consists essentially of e cylindrical body fastened againstturning to the IQ body or to the 3 tin -support of the vehicle, and abelt or anti one end or, which is secured to a norrretating part of theaxle of the vehicle, passes over the surface of cylindrical body, and isbrought down on the other side of the same, its free end being attachedto a resilient member, which is secured to e nonrotating portion of theaxle or .to the bod; of the vehicle.

Figs.- 4 and 5 illustrate er modification of the device, in which oneend of the belt or band;

is attached tov the body of the oer; Figs. 6 and 7 show anothermodification of the'device, while Fi s. 8 and 9 are enlarged see-r my;tional views 0? the device, shown in F igs, 6 and 7.

In Figs. 1 to 3, 1 is the frame Wh' h Blfir ports the body ofthe vehicleto which t e device is secured, and which rests uFon these main sprin s2. The shock control ing de vice, 6I11b0( .ied in the present invention,is inter )osod betweenthe body of the vehicle and t e axle or estationarilysupported part of the. running gear, being attached at its71} lower and u per parts, respectively, to said body and ex e ofrunning gear.

The shock absorbing device comprises a, cylindrical'body, such 'as adrumf i, haying. runs or flanges 5, 5 oncboth sides of thelssrneg m andsecured against rotation by screws f3, 61 A clip 7 is srranged on astationary part of the axle 3, and. fastened to the same in any suilahieway, is a non-resilient band or l-elt s, n'eierably made of caniels hairor any other non'stretching, material. The lzelt runs over the drum 4,covering about one-half of its cylindriral sur: face, by making aboutone-half turn around. the same. To the free end of this belt or bondisnttached in any n'ianner known in the art a resilient member 9, thelree end of which is secured to the clip '7 of the axle 3. In Figs, 1 3of the drawings, this resilient member. comprises a helical spring,adjustable to dii- 9e ferent weights and sizes of ehicles :1 ad, on theother hand, adording means to tightenor loosen the action of the nelt orbend The. dimensions of the ill; and s wring are such that the spring isheld in its almost extended 96 state, when the main syringe of thevehicle. are in their normal position and the spring. returns to itsnormal form, when the, main] s Jl'ings ol' the marriage are compressed.(l ig. 2). I 1001 In the modification shown in Figs' d undo; the lelt 8runs practically over the entire cj/ lindrical surface of the drum, andits spring-Q is fastened to the body of the car. i

Figs. 6 to 9 show still another modification; M of the device, In thiscase the drum 10 Rrises only one flange 11, while its otiier ange,preventing thel and or belt Sifrorn, slipping ofi the same. is formed bya cover inclosing said drum. The drum andtlieltqv cover, inclosing thesame, are fastened to the body of the car or to the spring-support bbolts 13, 13, havin heads 13', 13', \rhic bolts pass through the drumand cover. The drum and cover are held in place by nuts 14-14, securelyheld against rotation by a. nut-lock, suchv as it stud 15, passingthrough the bolt.

The l' elt 8 may i c secured to a stationary pa rt oi the running. gearl y means of :1. clip 7. whence it runs through an opening: is ol' thecover over the drum it), the opening H3 being: of a sullicient size toallow of n. play of the belt. The tree end of the lclt or band 8 isattached to u spiral spring: 17, one end 01' which forms a helicalspring; portion 18, Wound around it. stud 1t). lhis helical por tion isextended to the periphery of the drum and there secured to the elt orband 8. The other end 20 of the sprinp shits one of the projections 21,formed on the drum and arranged on the inner cylindrical surface of thesame. These projections ai low oi adjustment of the tension of thespring by bringing; the end 20 of the same in contact with another ofsaid projections.

When a wheel of the vehicle strikes an ob struction in the road, thesprin s 2, supporting the lyody of the vehicle, are compressed; the twoparts of the support of the s ring on the axle and on the frame of thevehicle are then brought closer together. When this occurs, the springs9 or [7, as the case may he, return to their normal position and theband or belt 8 slips irecly around the surface of the drum.

Oi: the immediate rebound or opening of the springs 2 of the vehicle,the bond and its spring. secured thereto, tends to cause a lraldngaction of a ro'ic wrap ed round a clcat or post, and it will 1e seentint a comparatively weak spring will cause a vastly augmented reactionor tension on the belt or band, as it tries to slip hack to its normalposition, when the spring 2 of the vehi ole opens. The braking actionthereby prevents the sudden upward throw of the vehicle body. It isobvious that the device does not aiiect the action of the vehicle springin comp essing, but prevents the reaction or rebound which very oftencauses broken s rings and uncmnfortable riding quiility on the .vehicleand the wcztr of the ruficr tires of the same. Thtwievice ac s, inotlici'words, t0 dam )(Ji the excessive upward throw or reliounil andllattcn out the curve of i l'ilr tions of the springs, so that there areno violent or rapid ruinges of moti ns ol the vehicle l ody. supportedly the springs.

It is obvious that the drum may l'e secured to the stationery part ofthe running gear, wh le the ends of the ielt may e secured to thevehicle lody o some other stationary part of the vcliici withoutdeparting: from the spi it and scope of the present invention.

It will be easilv set-1.. that instead ol the band 8 and resilientmember 9 a resilient hand may le. used.
